Identify your window style for replacement parts: awning windows hinge on the sides and open outward at the bottom; hopper windows hinge top or bottom and open inward; casement windows crank open to the right or left; single-hung have a fixed top sash with a movable bottom; double-hung allow both sashes to slide; horizontal sliders move sideways instead of vertically.

Step-by-Step Instructions

1. Why Window Type Matters

• When ordering replacement or repair parts, the most important thing to know is what type of window you have.
• The window style determines which hardware (operators, balances, hinges, locks) will fit.
• Use the descriptions below to identify your style before contacting us for parts.

2. Awning and Hopper Windows

• Awning windows are hinged on the sides and open outward at the bottom.
• Hopper windows are hinged on the sides like an awning but open into the interior of the home.
• Hoppers can be hinged at the top or the bottom depending on the design.

3. Casement Windows

• Casement windows are hinged on the sides at the top and bottom of the sash.
• They open and close using a crank mechanism (the operator).
• Casements swing outward to the right or to the left.

4. Single-Hung and Double-Hung Windows

• Single-hung windows have only one moving sash — the top sash is fixed and the bottom sash slides up and down.
• Double-hung windows allow both the top and bottom sashes to slide vertically.
• Because neither sash is fixed on a double-hung, both can be opened at once for maximum ventilation.

5. Horizontal Sliding Windows

• Horizontal sliders work much like single- or double-hung windows, but the sash rolls side to side instead of up and down.
• One or both sashes may be operable depending on the model.
• Once you have identified your window type, you can search for the matching hardware with confidence.
